How do I turn off a PV inverter?

Move the cursor to submenu “Turn ON/OFF”. Move the cursor to “Turn OFF” and ensure, then the inverter will be shut down. Automatic Turn ON/OFF: The inverter will start up automatically when the output voltage and power of PV arrays meet the set value, AC power grid is normal, and the ambient temperature is within allowable operating range.

How to connect a PV module to a DC inverter?

PV modules generate electric energy when exposed to sunlight and can create an electrical shock hazard. Therefore, when connecting the PV modules, shield them with opaque cloth. Before connecting DC input power cables, ensure that the voltage on the DC side is within the safe range and that the DC SWITCH on the inverter is OFF.

How do I fix a faulty PV inverter?

Correct PV string connection. Contact after-sales service personnel. Restart inverter by recycle both AC and DC switches. Wait for 1 minute between OFF and ON for all energy to discharge. Contact after-sales service personnel. Restart inverter by recycle both AC and DC switches. Wait for 1 minute between OFF and ON for all energy to discharge.

What happens if a PV inverter fails?

The inverter will be shut down automatically if the PV power generation system fails, such as output short circuit, grid overvoltage/under voltage, grid over frequency/under frequency, high environmental temperature or internal malfunction of the machine. The fault information will be displayed on the APP interface.

Can a PV inverter touch other parts?

Do not touch any other parts'surface except the DC switch when the PV inverter is operating; its partial parts will be extremely hot and can cause burns. Power OFF all electrical terminals before the inverter maintenance; strictly comply with the safety precautions in this document when operating the inverter.

How do I install a PV inverter?

Ensure there is no electronical connections around ports of the PV inverter before installing; Adequate ventilation must be provided for inverter installation location. Mount the inverter in vertical direction, and ensure that no object is put on the heat sink affecting the cooling. (For details, refer to Chapter 4 Installation)
